Intake VCP Hydraulic Control Valve

Intake camshaft position (CMP) actuator is connected to the intake camshaft and operated by the hydraulic pressure, which is
provided by the oil pump in order to change the intake camshaft to the CKP (CKP) relative angle. Intake VVT solenoid valve power
is provided from the main relay. ECM controls ground with a pulse-width modulation signal to control the engine oil flow to the
camshaft position actuator. Oil pressure moves a security slide valve within the camshaft position actuator body at the front of the
camshaft. When the safety slide valve moves, the oil is imported to the camshaft position actuator to rotate the camshaft. The intake
camshaft camshaft actuator change the camshaft working angle up to 50 degrees.

4. Diagnostic Steps:

Note

Before carrying out this diagnosis step, observe the data list on scan tool and analyze the accuracy of the data, as
these will help with quick diagnosis.

Step 1

Check whether there are control system DTC codes other than DTC P0011, P0012, P0016 and P0026.

(a)

Connect scan tool to the datalink connector.

(b)

Turn the ignition switch to "ON" position.

(c)

Press the scan tool power button.

(d)

Select the following menu items: Engine/Read DTC codes.

(e)

Read DTC codes.

Results:

Yes

DTC codes other than DTC P0011, P0012,
P0016 and P0026

No

No

Refer to

2.12.7.14

DTC Code Index

Yes

Step 2

Check the following items.

(a)

Check whether the oil viscosity is normal and whether the oil
is clean.

(b)

Observe the Engine oil level. Engine oil level should be within
the work range.

Engine

Control System JL4G15-D

(c)

Check whether the oil is changed in a timely manner and
whether the engine oil contains additives or viscosity is
incorrect.

No

Replace engine oil and oil filter. When
necessary, clean the engine lubrication
system.

Yes

Step 3

Check VVT solenoid valve resistance.

VVT Solenoid

FE02-5005b

(a)

Disconnect VVT solenoid valve wiring harness connector
EN10.

(b)

Measure resistance between the two VVT solenoid valve
terminals.

Standard Resistance: 10.5 Ω (68 ºF) at 20°C

No

Replace the VVT solenoid valve. Refer to

2.2.8.4

VVT Solenoid Valve Replacement and

Filter Cleaning

.

Yes

Step 4

Check the VVT solenoid valve actuator.

Note: In the testing process, it is strictly prohibited Connect two
wires directly together, otherwise it might cause an explosion, fire
or other dangers.

(a)

Connect the battery positive terminal to VVT solenoid valve
terminal No.1 and the negative terminal to the VVT solenoid
valve terminal No.2.

(b)

Check the filter movement.

Does the filter move?

No

Replace the VVT solenoid valve. Refer to

2.2.8.4

VVT Solenoid Valve Replacement and

Filter Cleaning

.

Yes

Step 5

Check VVT solenoid valve filter.
